PURPOSE: To decrease the load of a job processing processor, by performing the detection of interruption source generation of a terminal device and data READ/ WRITE processing with an AUTO-POLLING controlling processor.
CONSTITUTION: The job processing processor 2 sets A-POL information on an A-POL controlling table 6 and gives an A-POL processing start command to the A-POL controlling processor 3. The processor 3 gives a command for the start of A-POL to an A-POL controlling circuit 4. The controlling circuit 4 transmits the A-POL to a terminal device 8. When a response controlling circuit 10 receives the A-POL, the reception is informed to a processor 9. The processor 9 instructs the transfer of data of an A-POL response storing memory 12 to the response controlling circuit 10 to perform the data transfer. When the POL type requires data READ or WRITE, the processor 3 outputs a READ/WRITE issusing command to the A-POL controlling circuit 4 and when the response is received from the terminal, whether or not the processing of the commanded POL type is finished is discriminated.
